The straw cup of the present embodiment will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, the present embodiment provides a straw cup 010, which includes a cup body 100, a cup cover 110 and a straw 200, wherein the cup cover 110 is connected to the cup body 100, the straw 200 is connected to the cup cover 110, and one end of the straw 200 extends into the cup body 100; the cup 100 is used for containing liquid, and the straw 200 is used for sucking out liquid.

The straw 200 may also be connected to the cap 110 via a connector 160, and the connector 160 may be connected to the cap 110 in a manner including, but not limited to, snap-fit, bayonet, and threaded connection. Of course, in other embodiments, the straw 200 may be directly connected to the cap 110, and the connection manner includes, but is not limited to, screw connection, insertion connection, and integral molding.

Further, the straw cup 010 further comprises a suction nozzle 120, and the suction nozzle 120 is arranged on the cup cover 110 and is communicated with the straw 200; when drinking the beverage contained in the cup body 100, the user can suck out the beverage in the cup body 100 through the suction nozzle 120 and the suction pipe 200.

The connection of the suction nozzle 120 and the cap 110 includes, but is not limited to, a threaded connection and a plug-in connection.

Of course, in other embodiments, one end of the straw 200 extends into the cup 100, and the other end of the straw 200 passes through the cap 110 and is located outside the cup 100, so that a user can drink the drink contained in the cup 100 directly through the end of the straw 200 extending out of the cup 100.

To improve the hygiene of the straw cup 010; the straw cup 010 further includes a cup cover 130, and the cup cover 130 is connected to the cup cover 110 for covering the suction nozzle 120 between the cup cover 130 and the cup cover 110 or exposing the suction nozzle 120. Therefore, when the straw cup 010 is not used, the suction nozzle 120 is covered between the cup upper cover 130 and the cup cover 110, so that the problems of dust falling of the suction nozzle 120 and the like are reduced, and the sanitation degree is improved.

The connection of the lid 130 and the cap 110 includes, but is not limited to, a rotatable connection and a detachable connection.

In order to reduce the storage space occupied by the unused and stored straw cup 010; the spout 120 is configured to be rotatable or foldable relative to the cap 110.

In order to improve the problem that the liquid contained in the cup body 100 is easy to leak out from the space between the cup body 100 and the cup cover 110; a gasket 140 is disposed between the lid 110 and the cup 100.

The lid 110 and cup 100 may be connected by any means including, but not limited to, threaded connection, snap-fit connection.

To make the straw cup 010 easier to hold; the cup body 100 is further connected with a handle 150, and the connection mode of the handle 150 and the cup body 100 includes but is not limited to integral forming, splicing, bonding, threaded connection and sleeving.

It should be noted that the structure of the straw cup 010 not mentioned or described in detail is similar to that of the related art, and is not described herein again.

Referring to fig. 2, in the present embodiment, the straw 200 includes a straw body 210, a weight member 220 and a check valve 230, the straw body 210 is provided with a channel 211; the weight member 220 is connected to the straw body 210; the straw body 210 is connected with the cup cover 110, and the weight member 220 is positioned in a containing cavity of the cup body 100 for containing liquid; the check valve 230 is disposed inside the straw body 210 and near the weight 220, and the check valve 230 can open the channel 211 under the action of suction force and block the channel 211 when the suction force disappears. The non-return valve 230 is arranged close to the weight 220, enabling the non-return valve 230 to also be located inside the housing cavity of the cup 100; the check valve 230 can block the passage 211 of the straw body 210 when not receiving suction force, so that the problem that the liquid contained in the cup body 100 is easily accidentally ejected from the nozzle of the straw body 210 can be solved; moreover, the weight 220 is usually disposed near the end of the straw body 210, and the check valve 230 is disposed near the weight 220, so that the weight is closer to the end of the straw body 210, which can effectively prevent liquid in a cup from entering the straw body 210, thereby further improving the problem of accidental ejection of liquid from the straw body 210, even if liquid enters the straw body 210, the liquid needs to flow through a long distance to flow from the end of the straw body 210 close to the check valve 230 to the end far from the check valve 230, increasing the difficulty of accidental ejection of liquid from the straw body 210, and being beneficial to improving the problem of accidental ejection of liquid from the straw body 210. When the liquid in the cup body 100 needs to be drunk, the channel 211 of the straw body 210 can be opened by the check valve 230 under the action of suction force only by lightly sucking at the nozzle of the straw body 210 instead of sucking water through the straw body 210 after the check valve 230 is bitten by a user, so that the straw 200 is more convenient to use, is convenient to control the drinking flow, is not easy to choke water, and is more suitable for infants in the drinking stage.

The connection mode of the weight member 220 and the straw body 210 can be selected according to the requirement; in this embodiment, the weight member 220 may be wrapped in the material of the straw 200 formed by injection molding when the straw body 210 is injection molded, so as to connect with the straw body 210; thus, the number of assembling processes for connecting the weight member 220 to the straw body 210 can be reduced, and the assembling efficiency can be improved.

Of course, in other embodiments, the connection manner of the weight member 220 and the straw body 210 includes, but is not limited to, bonding, and screwing.

In order to ensure that the straw body 210 can be straightened sufficiently under the action of the weight member 220, and further, the liquid at the bottom of the cup body 100 can be sucked out through the straw body 210; the suction pipe body 210 is provided at both ends thereof with an outlet 212 and an inlet 213 communicating with the passage 211, respectively, and the weight member 220 is disposed adjacent to the inlet 213 of the suction pipe body 210. Thus, when the straw body 210 is inserted into the cup body 100 and the weight member 220 is located in the accommodating cavity of the cup body 100, the straw body 210 is ensured to be straightened sufficiently by the gravity of the weight member 220, the inlet 213 of the straw body 210 is ensured to be as close to the bottom of the cup body 100 as possible, and the straw body 210 can reliably suck out liquid when a small amount of liquid remains in the cup body 100.

Referring to fig. 2, the specific position of the non-return valve 230 disposed on the straw body 210 can be selected according to the requirement. In this embodiment, the weight member 220 has a first end proximate the outlet 212 and a second end distal the outlet 212; check valve 230 is located at a second end, i.e., check valve 230 is proximate to inlet 213 of straw body 210. Thus, the non-return valve 230 can more effectively prevent the liquid in the cup from entering the straw body 210, and the problem of accidental ejection of the liquid from the straw body 210 is solved; even if liquid enters the straw body 210, the distance between the check valve 230 and the outlet 212 of the straw body 210 is lengthened as much as possible, so that the liquid needs to flow through a longer distance to flow from the end of the straw body 210 close to the check valve 230 to the end far away from the check valve 230 and flow out, thereby effectively increasing the difficulty of the liquid being accidentally sprayed from the straw body 210 and being beneficial to improving the problem of the liquid being accidentally sprayed from the straw body 210.

It should be appreciated that in other embodiments, referring to FIG. 3, check valve 230 may also be located at the first end, or between the first and second ends (not shown).

The check valve 230 is disposed at a position close to the weight member 220, so that the check valve 230 is located as much as possible below the cup body 100; when the non-return valve 230 is not under suction, the non-return valve 230 can block the position of the straw body 210 close to the inlet 213, so as to effectively reduce the liquid accidentally entering the straw body 210, and further effectively improve the problem that the liquid is accidentally ejected from the outlet 212 of the straw body 210.

To avoid the need for a large suction force, check valve 230 can be caused to open passage 211; the inner diameter of the passage 211 is configured to be smaller than the caliber of the inlet 213. When the user sucks the liquid in the cup body 100, not only the suction force acts on the check valve 230, but also the liquid at the inlet 213 acts on the check valve 230, so that the check valve 230 can reliably open the passage 211 under the dual actions of the suction force and the liquid driving force, rather than singly driving the check valve 230 to open the passage 211 by using the suction force, the suction force required when opening the passage 211 can be reduced, and the user can be ensured to be more labor-saving when drinking the straw 200.

Referring to fig. 4, in the present embodiment, the check valve 230 includes a blocking piece 231, the blocking piece 231 is connected to the straw body 210, and the blocking piece 231 is provided with an opening 232; the blocking piece 231 can expand the opening 232 under the action of suction force to open the channel 211 of the pipette body 210, and can recover when the suction force disappears and shrink the opening 232 to block the channel 211. By opening the opening 232 in the blocking piece 231 connected to the straw body 210, when the liquid in the cup body 100 needs to be sucked out through the straw body 210, the blocking piece 231 expands the opening 232 under the action of the suction force to open the channel 211 of the straw body 210, so that the liquid in the cup body 100 can flow out through the straw body 210; when there is no suction force, the blocking sheet 231 can automatically return to the state of reducing the opening 232 and blocking the passage 211 of the straw body 210, so as to block the liquid from flowing through the passage 211, thereby improving the problem that the liquid in the cup body 100 accidentally flows out and is sprayed out through the passage 211 of the straw body 210.

It should be noted that the connection manner of the blocking piece 231 and the straw body 210 includes, but is not limited to, integral molding and adhesion.

Alternatively, the opening 232 provided in the shutter 231 may be a straight opening or a cross-shaped opening.

Referring to fig. 4 and 5, in the present embodiment, the blocking piece 231 includes a first blocking piece 233 and a second blocking piece 234, the first blocking piece 233 and the second blocking piece 234 are both movably connected to the straw body 210, and the first blocking piece 233 and the second blocking piece 234 both have free ends and together form an opening 232. When the liquid in the cup body 100 is sucked out by using the straw 200, the free ends of the first barrier tab 233 and the second barrier tab 234 are moved relative to the straw body 210 under the action of the suction force, so that the gap between the free end of the first barrier tab 233 and the free end of the second barrier tab 234 is increased, that is, the opening 232 between the free end of the first barrier tab 233 and the free end of the second barrier tab 234 is expanded, and the channel 211 of the straw body 210 is opened, so that the liquid in the cup body 100 can flow out through the channel 211 of the straw body 210; when the suction force is removed, the first and second blocking pieces 233 and 234 can be restored to the position of blocking the passage 211 to block the liquid in the cup body 100 from being accidentally ejected from the outlet 212 of the straw body 210 through the first and second blocking pieces 233 and 234.

Further, the first and second stoppers 233 and 234 are substantially D-shaped, the arc-shaped edges of the first and second stoppers 233 and 234 are connected to the straw body 210, and a linear opening 232 is formed between the straight edges of the first and second stoppers 233 and 234. The arc edges of the first blocking piece 233 and the second blocking piece 234 are connected with the straw body 210, so that the first blocking piece 233 and the second blocking piece 234 can swing relative to the straw body 210 under the action of small external force; thus, when the liquid in the cup body 100 needs to be sucked out by the straw 200, the first and second blocking pieces 233 and 234 are swung with respect to the straw body 210 and the opening 232 is expanded by only sucking lightly at the inlet 213 of the straw body 210.

It should be understood that, in other embodiments, referring to fig. 6, the blocking plate 231 includes four blocking pieces 231, and the four blocking pieces 231 are all connected to the straw body 210 and distributed along the inner circumference of the straw body 210 and form a cross-shaped opening 232.

In still another embodiment, referring to fig. 7, the blocking plate 231 is a circular plate, the outer periphery of which is connected to the inner wall of the straw body 210, and a linear opening 232 that does not penetrate through the outer periphery of the blocking plate 231 is formed along the diameter of the blocking plate 231. When the flap 231 receives the suction force, the flap 231 is deformed and expands the opening 232; when the suction force applied to the shutter 231 is lost, the shutter 231 can be restored and the opening 232 is narrowed.

In order to make the first blocking piece 233 and the second blocking piece 234 more easily swing under the suction force to enlarge the opening 232, further achieving the purpose of saving labor; under the condition that the first blocking piece 233 and the second blocking piece 234 are not affected by external force, the first blocking piece 233 and the second blocking piece 234 may be distributed at an included angle, and the included angle between the first blocking piece 233 and the second blocking piece 234 is distributed towards the inlet 213 of the straw body 210.

Optionally, referring to fig. 5, the included angle α between the first blocking piece 233 and the second blocking piece 234 is 45 ° to 150 °, for example: 45 °, 60 °, 75 °, 90 °, 100 °, 110 °, 120 °, 125 °, 130 °, 145 °, 150 °, etc.

Further, the first blocking piece 233 and the second blocking piece 234 are arranged at an angle regardless of whether the first blocking piece and the second blocking piece are subjected to suction force. Thus, when the liquid in the cup body 100 is sucked out by using the straw 200, the first blocking piece 233 and the second blocking piece 234 can swing under the action of the suction force to expand the opening 232, and after the liquid enters the channel 211 of the straw body 210, the first blocking piece 233 and the second blocking piece 234 can be further pushed away by using the liquid, so as to ensure the reliable and continuous suction of the liquid; when the liquid in the cup body 100 is not sucked by the straw 200, the first blocking piece 233 and the second blocking piece 234 are reliably reset under the dual actions of the self-weight and the liquid remained in the channel 211 of the straw body 210, and the opening 232 is reduced, so that the first blocking piece 233 and the second blocking piece 234 can be reliably blocked in the channel 211 of the straw body 210, and the liquid in the cup body 100 is blocked from being accidentally ejected through the straw body 210.

It should be noted that the included angle between the first blocking piece 233 and the second blocking piece 234 when the first blocking piece 233 and the second blocking piece 234 are not subjected to the suction force is larger than the included angle between the first blocking piece 233 and the second blocking piece 234 when the first blocking piece 233 and the second blocking piece 234 are subjected to the suction force; for example: the included angle between the first blocking piece 233 and the second blocking piece 234 when not receiving suction is 120 °, and the included angle between the first blocking piece 233 and the second blocking piece 234 when the first blocking piece 233 and the second blocking piece 234 expand the opening 232 by suction is 45 °.

It should be further noted that, when the first blocking piece 233 and the second blocking piece 234 expand the opening 232 by suction force, an included angle between the first blocking piece 233 and the second blocking piece 234 may refer to an included angle at which an extending surface of the first blocking piece 233 and an extending surface of the second blocking piece 234 intersect.

The size of the opening 232 may be set as desired; the aperture of the expanded opening 232 when the baffle 231 is subjected to suction is 2-8mm, for example: 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, etc.; the width of the opening 232 when the baffle 231 is not sucked is 0.05-2mm, for example: 0.05mm, 0.1mm, 0.15mm, 0.2mm, 0.4mm, 0.6mm, 0.8mm, 0.9mm, 1.0mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2mm and the like, and are not particularly limited herein.

In this embodiment, the width of the opening 232 is 0.05mm when the blocking piece 231 is not subjected to the suction force; when the baffle 231 is subjected to suction force, the aperture of the expanded opening 232 is 8mm; specifically, when neither the first blocking piece 233 nor the second blocking piece 234 receives suction, the width of the opening 232 between the two is 0.05mm; when the first blocking piece 233 and the second blocking piece 234 both receive suction, the opening 232 between the two is expanded to have a caliber of 8mm. Thus, when the blocking piece 231 is not subjected to the suction force, the gap of the opening 232 is extremely small, so that the liquid can be effectively blocked from passing through the opening 232 of the blocking piece 231, and the problem that the liquid in the cup body 100 is accidentally sprayed out from the outlet 212 of the suction pipe body 210 can be solved; when the blocking sheet 231 is sucked, the opening 232 can be expanded to a larger caliber, so as to ensure that the liquid in the cup body 100 can be reliably sucked out, and prevent the setting of the check valve 230 from interfering with the drinking of a user.

It should be noted that, when the first blocking piece 233 and the second blocking piece 234 are not subjected to the suction force, the free ends of the first blocking piece 233 and the second blocking piece 234 are arranged to have a certain gap, that is, a certain gap is formed at the opening of the blocking piece 231, so that the friction between the free ends of the first blocking piece 233 and the second blocking piece 234 can be reduced, and the first blocking piece 233 and the second blocking piece 234 can be ensured to reliably swing under the suction force and expand the opening 232.

Of course, in other embodiments, in the case that the first blocking piece 233 and the second blocking piece 234 are not subjected to the suction force, the free end of the first blocking piece 233 and the free end of the second blocking piece 234 abut against each other, that is, the width of the opening 232 is 0mm. In this manner, the liquid in the cup body 100 can be more reliably blocked from being accidentally ejected through the passage 211 of the straw body 210.

The thickness of the blocking piece 231 can be selected as required, so that the blocking piece 231 can be effectively blocked in the channel 211 of the pipette body 210, and the problem that liquid is accidentally ejected through the pipette body 210 is solved; the thickness of the blocking plate 231 may be 0.3mm to 1.5mm, that is, the thickness of the first blocking plate 233 and the second blocking plate 234 may be 0.3mm to 1.5mm, for example: 0.3mm, 0.5mm, 0.7mm, 0.9mm, 1.2mm, 1.4mm, 1.5mm, and is not particularly limited herein.

When the straw cup 010 of this embodiment is used, in the process that a user sucks the liquid in the cup body 100 through the straw 200, the non-return valve 230 disposed on the straw body 210 can automatically open the channel 211 of the straw body 210 under the action of suction force, so that the liquid can smoothly flow out through the straw body 210; when drinking water is not taken in the straw cup 010, the non-suction check valve 230 can be blocked in the channel 211 of the straw body 210, and liquid contained in the cup body 100 is prevented from being accidentally ejected from the outlet 212 of the straw body 210 through the channel 211 of the straw body 210.

To sum up, the straw 200 of the present invention can be used in the straw cup 010, which not only can improve the problem of accidental spraying of the liquid contained in the cup body 100, but also does not need to bite the mouth of the straw 200 when drinking, so that the straw is convenient to use, convenient to control the drinking flow, not easy to choke water, and more suitable for infants in the stage of learning to drink; and the straw cup 010 has simple structure, easy cleaning and controllable cost.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
